• "No-Solution" appears on the solution screen when no solution exists for
an inequality (such as X
2
< 0).
Ratio Calculations
The RATIO Mode lets you determine the value of X in the ratio expression
a : b = X : d (or a : b = c : X) when the values of a, b, c and d are known.
The following shows the general procedure for using RATIO.
1. Press
(RATIO) to enter the RATIO Mode.
2. On the menu that appears, select (a:b=X:d) or (a:b=c:X).
3. On the Coefficient Editor screen that appears, input up to 10 digits for
each of the required values (a, b, c, d).
• To solve 3 : 8 = X : 12 for X, for example, press in step 1, and
then input the following for the coefficients (a = 3, b = 8, d = 12): 3 8
12 .
• To change a coefficient value you already have input, move the cursor
to the appropriate cell, input the new value, and then press .
• Pressing will clear all of the coefficients to zero.
Note: The following operations are not supported by the Coefficient
Editor: , (M-), (STO). Pol, Rec, ÷R, and multi-
statements also cannot be input with the Coefficient Editor.
4. After all the values are the way you want, press .
• This displays the solution (value of X).
• Pressing again will return to the Coefficient Editor.
